35th DAE Safety & Occupational Health Professionals Meet-2018

The 35th

DAE Safety & Occupational Health Professionals Meet-2018 was jointly hosted by the Atomic Energy Regulatory Board (AERB) and Variable Energy Cyclotron Centre (VECC) from 27 to 29 November, 2018 at Kolkata.

2 Prototype EPICS Based Temperature Data Archive & Monitoring on 218S Platform

In SST-1 Cryogenic division, 80 K thermal shields temperatures especially on 80 K baffles need critical monitoring and data logging. A commercial temperature monitor is being used frequently for this purpose. This monitor is specially designed for low temperature sensor applications and has 8 channels in single unit, and is also equipped with RS-232 and GPIB interface for data communication.

IPR Data Acquisition and Control Division (DAC) and SST-1 Cryogenics Division have made collaborative efforts and devel-oped in-house system with taking care of future expansion by using Open Source software tools EPICS and CSS. The EP-ICS based data acquisition system on Linux platform has been developed with data acquisition rate of 1 sec. The open source data base MySQL has been used for data logging. The system is developed in such a way that it can be extended for N numbers of the monitors.

Temperature data can be monitored from any PC on the network using a web browser without any additional software instal-lation. The proof of concept, EPICS based monitoring system in function and is ready to be deployed for any project. The MySQL SCADA interface has also been successfully demonstrated. - Vishnu Patel (DAC) and Dashrath P. Sonara, SST-1 Cryogenic division.

Automation of LN2 Storage Tanks of SST-1 Cryogenic System at IPR

The cryogenic system of SST-1 consist of helium cryo plant system along with its sub-systems and liquid nitrogen (LN2) dis-tribution system. The LN2 distribution system consists of three numbers of storage tanks (capacity of 35,000 litres each), 250-m long cryo transfer lines, sub-cooler Dewar, distribution for cryo and other miscellaneous application viz., SST1 80K thermal shield, integrated flow distribution and control (IFDC) and current feeder system (CFS). The storage tanks are in-stalled 250m away from control room and have a manual pressure and level measurement and control system. The control of pressure in LN2 management system is very essential in order to maintain 80K shield temperature. Manpower is essen-tial to manipulate the pressurization and vent system of LN2 storage tank having manual valves for maintaining tank pres-sure. In order to reduce manpower and for ease of operation from control room, automation and remote operation of the pressurization and vent of LN2 storage tank was initiated. This was implemented by PID loop in PLC and SCADA program-ming. Rohit Panchal, SST-1 Cryogenic Division

Ms. Hetal D. Pathak who is working in Administration Section as Office Clerk “B” was awarded the “Outstanding Staff Mem-ber of the Year 2018 (OSMY). Ms. Pathak joined the Institute on 22.8.2012. Initially she was handling Dispatch Section wherein she, on her own, made the whole section digital by doing entry in the computer and also maintaining hand written dispatch entries. Her ability to work and develop excel sheets required for dispatch need a special mention. Since February 2018, she has been handling IPR Identity Cards wherein again she developed the computerized Identity-card in place of hand written card, for the Project Students & visitors. Ms. Pathak also did a lot of work in Hindi, specially making most of the forms, letters, etc. bilingual and it was she who set the ball rolling for the work in Hindi, that others followed her

suit and Admin 2 Section got the first prize for working in Hin-di during January 2018. She has shown utmost sincerity and diligence and has displayed her meticulous and systematic outlook towards the tasks in hand. She plans and under-stands the work and also successfully completes the work in the stipulated timeframe. Her zeal to develop perfection and excellence is appreciable. In addition, Ms. Pathak’s is excep-tionally good in working on Computers (MS Office) & her knowledge & zeal for working in Hindi needs a special men-tion. Ms. Pathak has impressed most of the staff members be-cause of her pleasant demeanor and soft nature. She is a self-motivated person and is always focused on the work en-trusted to her, and this quality has never made anyone feel that she physically challenged. On behalf of IPR, the News-letter congratulates her on this achievement !

6 ADITYA-U Plasma Discharges Repeatability With Positive and negative Converter

Positive Converter : ADITYA Upgrade discharges repeatability was established with the application of horizontal plasma position control using two pairs of fast feedback coils powered by a dual polarity fast feedback power supply and ex-cellent wall conditioning in toroidal belt graphite limiter configuration. The minimum base pressure of ~9 x 10

-9 Torr was

achieved. The time evolu-tion of ADITYA Upgrade discharges parameters such as loop voltage (V), plasma current (kA), Ha line intensity (a.u.), Hard X-rays (a.u.), Soft X-rays and gas puffs represents

the discharges repeatabil-ity in ADITYA-U. The Plasma current of the or-der of ~90 – 100 kA and duration of ~ 80 – 90 ms was obtained. Only the positive converter was operational during these shots. So, the maximum Volt-sec was available up to ~80–90 ms.

Negative Converter : Another ADITYA-U Vacu-um vessel baking cycle was successfully carried out from 14th -16th No-vember, 2018 for maxi-mum temperature ~130° C (44 h continues) including 2 cycles of Hydrogen Glow Discharge Cleaning (GDC). Two major leaks, one in wire seal of (10-6 Torr) and one in PL-2 pump-ing line of (10-4 Torr) have been observed on 16th November, 2018. After solving all leaks minimum base vacuum of the or-der of ~ 5.6 x 10-9 Torr has been obtained for the first time in ADITYA-U tokamak. The available Volt-sec has been in-creased by adding a negative converter, with current -6 kA to -10 kA, to the positive converter having 12 kA to 12.5 kA of cur-rent in order to increase the discharge duration. The positive and negative converters are coupled using a thyristor based dual polarity converter with a circulating rectifier for the smooth transition from positive to negative converters. The time evo-lution of ADITYA Upgrade discharges parameters such as loop voltage (V), plasma current (kA), Ha line intensity (a.u.), and Hard X-rays (a.u.) represents plasma pulse length enhancement with negative convertor operation.
